Summary
Description ShockleyQueisserFullCurve.svg |
English:
The Shockley-Queisser limit for the maximum possible efficiency of a solar cell. The x-axis is the bandgap of the solar cell, the y-axis is the highest possible efficiency (ratio of electrical power output to light power input). (Assumes a single-junction solar cell under unconcentrated light, and some other assumptions too.) The curve is wiggly because of IR absorption bands in the atmosphere: I used the actual AM1.5G solar spectrum data. Sometimes people approximate the solar spectrum by a 6000K blackbody spectrum instead, and they get a smoother curve with slightly different values. I cross-checked my curve with independently-calculated ones and they agree to high accuracy,

I did the calculation in Mathematica, plotted it in Origin, and did PDF-->SVG conversion in Inkscape. Then a few years later, I ported the code from Mathematica to Python, and you can now see the whole calculation and results at https://github.com/sbyrnes321/SolarCellEfficiencyLimits/blob/master/sq.ipynb
